Xcmg Excavator Piston Pump
The piston pump is a commonly used booster pump, which is composed of a piston and a cylinder, and is widely used in the delivery system of hydraulic fluid to increase the pressure of the fluid. The piston pump realizes the suction and pressure of the fluid by changing the relative displacement of the piston and the cylinder. Piston pumps are suitable for hose pumps as well as closed shaft seal pumps. According to different construction structures and connection methods, piston pumps can be divided into three types: single-piston pumps, double-piston pumps and multi-piston pumps.
Principle of piston pump
The piston pump realizes the operation of the pump by changing the relative displacement of the piston and the cylinder. The hydraulic principles of the single-piston pump and the double-piston pump are the same, but the operating speed of the double-piston pump is faster than that of the single-piston pump. many.
When the piston at the front end is pushed onto its arm, it will compress the cylinder connected at the other end, and if the other piston is pushed onto its arm, it will expel the compressed air into the compressed cylinder, thereby Circulation to realize the operation of the pump. The flow rate and pressure of the fluid can be changed by adjusting the displacement of the piston and cylinder.
The main purpose of the piston pump
- The piston pump is mainly used in the hydraulic system. It can realize the delivery of hydraulic fluid and can change the pressure and flow of the fluid to meet the requirements of the system.
- Piston pumps can be widely used in hydraulic systems in industries such as automobiles, machine tools, ships, electric power, and metallurgy to drive and control the operation of various living devices, such as hydraulic cylinders, hydraulic motors, etc.
- Piston pumps can also be used in various hydraulic oil systems, such as tractors, excavators, cleaning equipment, hydraulic wrenches, etc., to adjust the pressure and flow of hydraulic oil.
- The piston pump can also be used in hydraulic transmission devices, such as hydraulic transmission vehicles, hydraulic motors, hydraulic drive vehicles, etc., to achieve pressurization and control of the hydraulic system.
- Piston pumps can also be used in hydraulic control systems, such as hydraulic control valves, hydraulic control cylinders, etc. The pressure regulation and flow regulation of the hydraulic control system can be realized through the piston pump.
